To all whom it may cm2/cern:

Be it known that THoMAs REDMAN, a subject of the King of Great Britain and Ireland, and a resident of The Priory, Bolton, Bradi ford, in the county of York, England, have invented certain improvements in and Relating to Apparatus for Purifying Gas,(for which l have obtained provisional protection in Great Britain, No. 105, dated January 2, 1904,) of which the following is a specification.

The object ot' this invention is to construct and combine with tanks applicable for the puriication of gas mechanism by which nurifying-tanks may be readily removed from or placed in connection with a range of gas-pipes leading to and from the purifying-tanks by adapting the said tanks so that they may be mechanicallyv emptied of the purifying agency placed therein and expeditiously refilled by apparatus constructed and arranged in such a manner as to assist in the revivitication, breaking up, or pulvcrizing oi' the oXid or like purifying material and to deposit such material in an etlicient manner when desired in a puritying-tank.

in describing my invention in detail reference is made to the accompanying drawings, in which-- Figure 1 represents an elevation of a gaspurit'ying tank, shown in position in relation to a gas-supply range or' pipes. Fig. 2 is an end elevation of same. Fig. 3 is aview showing a purifying-tank suspended for conveyance into a position ready for emptying. Fig. 4 is an end view of same and mechanism suitable for lifting and conveying the tank. Fig. 5 is a diagrammatic elevation, drawn to a reduced scale, showing a series of purityingtanks, along with lifting and conveying apparatus, pulverizing and revivitication screens, and suitable means for reiilling the tanks. Fig. 6 is a front View showing a portion of the screens; Fig. 7, a side elevation ot' a hopper, partly in section, adapted 'for receiving and assisting in the breaking' up and revivilication of the oXid and lifting same to an elevation; and Fig. 8 is an end view of same.

In carrying out my object the inlet and outlet branches 1 and 2 of the gas-pipes leading to and from a purifying-tank 3 are provided with iianges corresponding with those of the purifying-tank at A and B, and are so arranged that when a tank 3 is placed in position on the said branch pipes, as shown, with suitable flexible joint-'forming material between the respective flanges, gas-tight joints are formed without the aid of bolts or the like for nipping sarne together. The interior of cach tank is aranged t'or the reception of grids, ashitherto, Jfor supporting the oxid or other purifying material The cover et each purifying-tank 3 may be jointed to the tank by placing a. belt of iiexible material., such india-rubber, between tank 3 and lid 4, which when tightened together forma gas-tight joint independent of an ordinary lute-joint.

In order that purifying-tanks 3 may be mechanically emptied instead of having to delay the operation of emptying until the gas fumes have to some extent passed ott' or subsided and ot' persons having, as litherto, to get inside the tanks and throw out the purifying material by hand labor, l. secure to each end of a tank 3 a strengthening-platc 5, from which projects a trunnion 6 at one end ol tank and a trunnion 'Y at the other end of a length suitable for the reception ot' a spurwheel 8, arranged to engage with a featherkey ot' the ordinary description sunk in said trunnion in a manner that the wheel be readily placed and secured thereon or removed when necessary. The trunnions are applicable for the reception of lifting-bars 9, connected to pitch-chains 10, which pass over and engage with the teeth of sprocket-wheels 11,.forming part of the lifting-gear, hereinafter described, mounted on girders 12, placed above the range of puritying-tanks 3.

rEhe frame-plates 13 ot before-mentioned lifting-gear are mounted on pulleys 14, resting on girders 12, and projecting from one of the frame-plates 13 is a shaft or stud 15, upon which is mounted a grooved pulley 16 and a spur-pinion 17, secured together. Around the grooved pulley is an endless rope 18, guided by the small pulleys 19 and 20, both of which are supported on studs attached to brake-arm 21, supported by a pin at 22 and provided with a brake-block engaging with ico IOl

Eder-I pulley-groove at 21A. On pulling the endless rope i8 in the direction of arrow in Fig. tt it will be understood that the brake-arm 2l will be operated on before-mentioned pin and block 2l" raised clear of the 'pulley-groove, allowing thc pulley to be rotated; butvon pulling downward at 18" the otheil hanging' portion of rope the brake-block will be brought into tight contact with the `groove of pulley, the said block continuing to act as a brake when the rogjie is free andarin 2l in its normal position. On rotating' grooved pulley 1G and spur-pinion 'i7 the latter gearing, with spur-wheel 23, secured on shaft 524, is ro-- tated, also the sprocket-wheels 1l, secured on said sha'lt. Pitch-chains l0 engage with the sprocket-whcels 'l1 and pass under guidingpulleys il", mounted on a shaft or stud sup ported by 'lii'ainc-i'rlates 13, so that on the ro tation ol'i sprocket-wheels the pui'ifying'tanl 3, suspended by thepitch-chains, is raised or lowered and when raised, as shown by Figs. 3, d, and 5, may be conveyed on girders 12 on the rotation ol' grooved pulley ist* to the position required for mechanically emptying' theI tank, such as over hopper 24, which is provided with a number of. angular cross-bars 9A", attached to theinterior oi hopper. When a lid 4t removed and a purifying-tank 3 lifted. to the position shown by Figs. 3, 4, and 5, the trunnion 7 engages with a recess Aformed at thc bottom end of one of the irame-plates 13, as shown. llhe spur-wheel 3, mounted on trunnion 7, is then in gear with pinion 25, attached to grooved pulley 26, suitably supported by a stud projecting Yfrom one oli the li'a1ne-i ')lates 13, so that on conveying' same on girders to the position required and rotating thc grooved pulley 26 the spur-wheel 3 is operated and tank 3 turned into position for emptying' same of its purifying niaterial into the hopper 24. The material lalling upon the angular cross-bars 245" assists in breaking up and pulvcrizing the material. These angular bars are lixed within the hopper at an inclination, and at each end ot' the bars is an opening' through the hopper-walls con'imunicating with the under side olE therespective angular cross-bars, thereby aiiording means tor the outlet of Jfumes and inlet of fresh air for assisting' in the rei-rivification ot' the oxid. By arranging the angular crossbars 24E" at an inclination, as shown, some oit' the lumes escaping' from the oxid during reviviiication rising from the material below the angular cross-bars 245 gather in the channels formed on the under side ot' said bars, thereby allowing the vfumes to more readily escape at the upper ends oi' the respective inclined cross-bars, and thus reduce the liability of stagnancy, as would otherwise be the case should the bars be placed horizontal.

vlt will be obvious that by placing the angular bars 2e at an inclination and the fumes escaping in the manner described lfresh air will enter at the bottom ends at the lower inclination of said angular bars and that some ot the fresh air will spreal into the material by escaping Linder each open edge et' the bars; and on the air rising through the deposited material the action el roviviiication is commenced immediately the material leaves a purifying-tank 3 atter emptying in the manner described, after which the tank is ready to be replaced in its position, relilled, and set to work again in a considerably less space of time than when emptied and relilled in the manner as hitherto.

The hopper 24 and deposited contents may be raised from the position shown by dotted lilies to that shown by lull lines in Fig. 5 by lifting-gear similar to that already described,

and when raised on opening' a hinged door 241' the spent purifying material is allowed to escape into hinged chute 27 to the inclined screens or grids 23, the length ol' which is divided into a series et compartments by hinged doors 29, a step or drop being' 'formed at 29A between one compartment and another, so that on allowing the purifying material to slide or drop 'from one\coinpartment to another the tendency el such is to open out and change the position ot' the material and remove. the clogging by the turning action given to it on 'falling over the steps, the line particles dropping through the screens 28 to a series Q8" of liner mesh, which may be ar ranged with similai1 steps and hinged doors 29" 'for the purpose, as before described, or left straight, as shown. ln either case the line pulverized material drops through lower screens 28 to a non-perforated chute 30, which may be provided with similar steps and hinged doorsor left straight, as shown.

Above the licor, level with girders 1:2, is another set of gi rders 3l, forming traveling' lines, supporting what l term a "traveling measuring-hopper 32, provided with doors at the bottom. (Shown open by dotted lines rlhcse may be secured. horiz 'eta-ily in any convenient manner to form the bottom of measuring-hopper 3 into which the requisite quantity of disintegrated and. revivih'ed pi'lrifying material Afrom the before-mentioned chutes is deijiosited, and afterward emptied into a hopper 34, supported on girders i2 by pulleys 35, the outlet of said hopper being by preference a narrow trunk 36 ot' a length equal to about that of a purifying-tank, a suitable hinged retaining bottom or stop being' provided at the base of hopper immediately above the narrow trunk for l'iolding the material within the hopper until it is to be emptied.

One of the axles of carriage supporting hopper 34. is provided with a groei/ed ropepulley 37, on the rotation of which the hopper may be traversed to and fro Jfor evenly distributing the pulverized purifying material within 'a tank 3, or the trunk 36 may be suspended by hinges or the like and oscillated over the tank for distributing' and evenly spreading said material.

From the foregoing description it will be .seen that the emptying' of purifying-tanks 3, 'the pulverizing and placing in position ef the 'purifying-oxid for reviviication, and the refilling of the tanks are all effected by mechanical means combined together in a novel imanner to work in unison for the purpose described.

i lWhat l claim as my invention is- 1. In combination, a purifying-tank, meehanism above the samefor lifting the said tank, said mechanism being movable in its elevated position to convey the tank, means for emptying the tank, a receptacle for receiving' the material from the tank and for breaking up and revivifying the said material, and means for directing the material back to the tank, substantially as described.
